WooCommerce PDF Watermark

I had asked before to add the option to add a note about the downloadable PDF having a password and instructions.

It now includes a note saying that if it is password protected the password would be either the order id or the email address.

It would be better to sense that the PDF will be protected or not and which option was used for the password. Then the note could be more direct and say:

Your downloaded PDF is password protected. The password is the email address you entered for this order as indicated below.
